Notes:
Version 2:
- fix a ton of memory leaks (I assumed that virXMLGetProp returns static
strings)
- Add new device type to even more places
- Fix error message c&p error
- Fix memleak in RNGDef free func

Is this an inherent limit of qemu? For that matter, is it an inherent
limit, and no hypervisor can ever support more than one? In the bare
metal case, can't you plug in multiple rng hardware dongles?
AFAIK qemu is able to support multiple RNG devices but I didn't find
that particularly useful. I will follow up with a patch that will add
support for more than one RNG device, although I don't think it will be
used much.
